Engineered by Harley-Davidson for the classic motorcycle segment, the 1973 Harley-Davidson FLH 1200 Super Glide relies on a 1206 cc (73.6 cu in) air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 58 HP (42.3 kW) at 5,150 rpm while maximum torque reaches 94.9 Nm (70 lb-ft) at 4,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 48.1 HP per liter and a 1,150 rpm working window between peak torque (4,000 rpm) and peak power (5,150 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the FLH 1200 Super Glide measures 345 kg (761 lbs) wet (curb), translating to a power-to-weight ratio of 0.17 HP/kg (5.95 kg per horsepower). The 19-liter (5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 135 km/h (84 mph).
